The Diablo III Website offers another new "In-Development" video on Class Skills in Blizzard's upcoming action/RPG sequel. Word is: "Doing battle with the Burning Hells means fighting fire with fire, and this week’s videos are all about destruction. We’ve got skills to tear through demonic invaders with summoned zombies and locusts, pepper them with knives and arrows, warp their minds, blow their bodies apart, and more. Watch, enjoy, and remember: heroes use every tool at their disposal in the pursuit of victory."

There will not be any hacks in Diablo3 that allow any kind of world alteration, and this includes items.

The game's networking (and everything else) looks iterated directly from WoW, and the only real "hacking" in WoW was that of gold farming and a few lag exploit tools (movement).

And possibly something about seeing through walls. Not very useful in D3.

But duping items... is very 2001. Diablo2's Closed B.Net was still very flawed and had to cut corners to accomodate modem users. In this day and age, a lot more stuff is offloaded to the server, making rampant cheating impossible.

Sure, aimbots are still possible in client-server games, but that's for FPS - an aimbot in D3 would be sort of useless.
